* [IB] mthca: SRQ limit reached eventsRoland Dreier2005-10-17
| | | | | | | | | Our hardware supports generating an event when the number of receives posted to a shared receive queue (SRQ) falls below a user-specified limit. Implement mthca_modify_srq() to arm the limit, and add code to handle dispatching SRQ events when they occur. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] mthca: Fill in more fields in query_port methodJack Morgenstein2005-10-17
| | | | | | | | Add code to fill in the bad_pkey_cntr, max_mtu, active_mtu and subnet_timeout fields in mthca_query_port(). Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

| | | | | | | Add abi_version attribute to uverbs class devices to allow for ABI versioning of device-specific interfaces. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] mthca: Report correct atomic capabilityJack Morgenstein2005-10-17
| | | | | | | Return correct atomic capability flag from mthca query function. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] mthca: fix hw_ver value returned from mthca_query_deviceJack Morgenstein2005-09-27
| | | | | | | The IB spec defines the field to be 32 bits, not 16 bits. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB: move include files to include/rdmaRoland Dreier2005-08-26
| | | | | | | | Move the InfiniBand headers from drivers/infiniband/include to include/rdma. This allows InfiniBand-using code to live elsewhere, and lets us remove the ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles. Signed-off-by: Roland Dreier <rolandd@cisco.com>

* [PATCH] IB/mthca: Report correct max_msg_szRoland Dreier2005-08-26
| | | | | | | | Set the max_msg_sz port property correctly in mthca's port_query function. Also zero out the attr struct so that we don't leave any other members uninitialized. Signed-off-by: Roland Dreier <rolandd@cisco.com>

* [IB/mthca]: Use io_remap_pfn_range for PCI spaceMichael S. Tsirkin2005-07-27
| | | | | | | Use io_remap_pfn_range to remap IO pages (remap_pfn_range is for memory). Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* [PATCH] IB uverbs: add mthca mmap supportRoland Dreier2005-07-07
| | | | | | | | | | | | | | Add support for mmap() method to mthca, so that userspace can get access to doorbell registers. This allows userspace to get direct access to the HCA for data path operations. Each userspace context gets its own copy of the doorbell registers and is only allowed to use resources that the kernel has given it access to. In other words, this is safe.

* [PATCH] IB/mthca: add support for new MT25204 HCARoland Dreier2005-04-16
| | | | | | | | | | | | | Decouple table of HCA features from exact HCA device type. Add a current FW version field so we can warn when someone is using old FW. Add support for new MT25204 HCA. Remove the warning about mem-free support, since it should be pretty solid at this point.

* [PATCH] IB/mthca: encapsulate mem-free check into mthca_is_memfree()Roland Dreier2005-04-16
| | | | | | | | | Clean up mem-free mode support by introducing mthca_is_memfree() function, which encapsulates the logic of deciding if a device is mem-free.

* [PATCH] IB/mthca: add fast memory region implementationMichael S. Tsirkin2005-04-16
| | | | | | | | | | | | | | Implement fast memory regions (FMRs), where the driver writes directly into the HCA's translation tables rather than requiring a firmware command. For Tavor, MTTs for FMR are separate from regular MTTs, and are reserved at driver initialization. This is done to limit the amount of virtual memory needed to map the MTTs. For Arbel, there's no such limitation, and all MTTs and MPTs may be used for FMR or for regular MR. Signed-off-by: Michael S.

* [PATCH] IB/mthca: clean up mthca_dereg_mr()Roland Dreier2005-04-16
| | | | | | | | | | It's cleaner to kfree mthca_mr, and not rely on the fact that ib_mr is the first field in mthca_mr. Signed-off-by: Michael S.

* [PATCH] IB/mthca: allow unaligned memory regionsMichael S. Tsirkin2005-04-16

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
